So you find yourself getting all into a recipe when you realize that it requires buttermilk to which you have none. I am sure that I am not the only person that has had this happen to them and the worse part is that I usually do not want to make a trip to the store for this. I will share with you that I am one of those people who spends plenty of time in my kitchen cooking up all sorts of goodies, yet I rarely...and I mean almost never...have buttermilk in my refrigerator.
It is just something that I use so few times that it just does not make sense for me to purchase it because I will just end up throwing it out once I move it one too many times in my refrigerator or it goes bad. I am not even sure buttermilk even goes bad because it is already a sour dairy product. See you probably know more about buttermilk than I do. Please do not revoke my baking card for this behavior.
As a way to try to redeem myself and my baker card I will tell you that I do substitute buttermilk for my own made ready substitute. There are a few different options to make this happen and the first one you may have already known about which is to add 1 Tablespoon of white vinegar to 1 cup of skim, low-fat, or whole milk. You will want to stir this and let it rest at room temperature for at least 2 minutes. This will make a 1-cup measuring of buttermilk, so if you need more then simply add an additional teaspoon of vinegar to each additional 1 cup of milk.
Next you can substitute the white vinegar for fresh lemon juice (non of that bottle stuff please). Take 1 Tablespoon of lemon juice and add it to 1 cup of skim, low-fat, or whole milk. Stir and let it rest at room temperature for 2 minutes. Again this will make a 1-cup measuring so if you need more then add an additional 1 teaspoon of lemon juice to each additional cup of milk.
Now if you have cream of tartar in you kitchen then you can mix 1 & ¾ teaspoon of cream or tartar to 1 cup of milk. Now with this you will want to mix the cream of tartar with a small amount of milk first until it dissolves to keep the whole thing from being lumpy.
Lastly if you want to keep it so simple then mix ¾ cup of plain yogurt or sour cream with ¼ cup of milk and stir...you cannot get any easier than that.
So there you have it...not one...not two or three...but four different ways to make a substitution for buttermilk that will save you the time of making an extra trip to the store.
Hope this helps.
